Merge tag 'irq-core-2022-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull interrupt updates from Thomas Gleixner: "Core code: - Provide a generic wrapper which can be utilized in drivers to handle the problem of force threaded demultiplex interrupts on RT enabled kernels. This avoids conditionals and horrible quirks in drivers all over the place - Fix up affected pinctrl and GPIO drivers to make them cleanly RT safe Interrupt drivers: - A new driver for the FSL MU platform specific MSI implementation - Make irqchip_init() available for pure ACPI based systems - Provide a functional DT binding for the Realtek RTL interrupt chip - The usual DT updates and small code improvements all over the place" * tag 'irq-core-2022-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (21 commits) irqchip: IMX_MU_MSI should depend on ARCH_MXC irqchip/imx-mu-msi: Fix wrong register offset for 8ulp irqchip/ls-extirq: Fix invalid wait context by avoiding to use regmap dt-bindings: irqchip: Describe the IMX MU block as a MSI controller irqchip: Add IMX MU MSI controller driver dt-bindings: irqchip: renesas,irqc: Add r8a779g0 support irqchip/gic-v3: Fix typo in comment dt-bindings: interrupt-controller: ti,sci-intr: Fix missing reg property in the binding dt-bindings: irqchip: ti,sci-inta: Fix warning for missing #interrupt-cells irqchip: Allow extra fields to be passed to IRQCHIP_PLATFORM_DRIVER_END platform-msi: Export symbol platform_msi_create_irq_domain() irqchip/realtek-rtl: use parent interrupts dt-bindings: interrupt-controller: realtek,rtl-intc: require parents irqchip/realtek-rtl: use irq_domain_add_linear() irqchip: Make irqchip_init() usable on pure ACPI systems bcma: gpio: Use generic_handle_irq_safe() gpio: mlxbf2: Use generic_handle_irq_safe() platform/x86: intel_int0002_vgpio: Use generic_handle_irq_safe() ssb: gpio: Use generic_handle_irq_safe() pinctrl: amd: Use generic_handle_irq_safe() ...
